My present invention comprehends the comranged along the sides of the car or other rebination, with such a system of heating, of a quired position. IVhen the car-stove is in 0pvessel or series of vessels located withina car eration, the direction of the incoming air is as containing a body of material capable of abdescribed, and the air, in traversing the duct 20 sorbing heat and of subsequently radiating J, passes over the storage-vessels K, impartthe same. In other words, I combine with ing a certain portion of its heat to the matethe air-heating system described a reservoir rial within the drums K, which may be any for heat from which the heat will be radiated material, liquid or solid, which will absorb when the primary source of heat is cut oit' heat. I may thus employ within the'storage- 2 5 as, for instance, when a car is detached from drums a solidsuch as the acetate of soda or the locomotive, from which the primary potash, which is fluid at a high temperasource of heat is derived. ture-or I may use a solution of salt in water In the accompanying drawings, which illusor a solution of any other salt, or simple watrate my invention, similar letters of referter may be utilized. For all practical pur- 0 ence indicate like parts. poses a saturated solution of salt in. water is Figure .l is a vertical longitudinal section all that is required, as it has a considerable of a railway-car, and shows an air-heating capacity for absorbing heatand willnot freeze drum under the car, the means by which the at any temperature. air and primary source of heat are brought The drum I prefer to fill with a solution or a 5 to the drum, the heated air therefrom carried material, to which it is likely to be subjected, 8 5 to the interior of the car and over the vessel to within approximately nineteen-twentieths within the car which contains the heat-abof its capacity, the space left being sufficient sorbin g material. Fig. 2 is aplan view showto compensate for any expansion of the maing the position of the drum under the'car terial within the vessel. Vhen the stove is 40 and the location of the storagevessels within not in use,the valve L in the pipe H is turned the car.

The stiorag'ewessels l have shown as Ioeated within the airtlues .l, whieh are arranged along the sides oli I do not, however, limit myself to any partieular loeatiit'm.

I claim as my invention- 1. A ear-heater etnnprising' a stove Within the ear, an air-induction pipe, an eduetionpipe for the heated air, and one or more elosed vessels eontaining' a 'liodv ot' heat-ahsm'bi11g material.

with the air-heating drum thereof, of an air i nduetion pipe, an eduetimi-pi iie forthe heat:- ed air, and one or more closed vessels eont'aining a body of lieat-absorhing material.

neeted to said stove and drum, and a closed vessel or vessels containing a heat-absorhing material, so located as to be heated by the heated air conveyed by the eduetvion-pipe.

5. A ear-heater comprising a stpve Within a car, an air-heating drum independent of the stove, an airinduet;ion and air-eduetwiou pipe connected to said stove and drum, a closed vessel or vessels containing a heatahsorbing' mz'rterial, and a valve in the induetvion- 'ii 'ie, whereby the stove or heating-druin may be operated independently of each other.
